SMA SC 500CP XT - Manual (Page 35)

Procedure:
1. Switch the inverter to Stop (see Section 5.2.1, page 51).
2. Connect the supply voltage (see Section 5.3.1, page 53).
3. Set the hygrostat to the minimum value. To do this, pull the selector switch out slightly.
Tip: the hygrostat is adjusted correctly if the relay of the hygrostat emits an audible click.
4. Check whether the heating elements are radiating heat after a delay time of five minutes.
If the heating elements are not radiating heat, contact us (see Section 13 "Contact", page 154).
5. Reset the hygrostat to the initial value. To do this, press the selector switch back towards the hygrostat. The initial
value of the hygrostat is indicated in the circuit diagram.
4.6 Configuration
4.6.1 Configuring the Network Settings on the Computer
Before your computer can communicate with the inverter, you must set the computer to the network settings of the
inverter. The network settings include the IP address, subnet mask, gateway and DNS server address.
The communication interface of the inverter has three LAN interfaces to the connected nodes. The IP address to be
configured in your computer depends on whether the computer is connected to the service interface of the inverter, the
control network or the monitoring network.
Network Default IP address
LAN1: Service interface of the inverter 192.168.100.2*
LAN2: Control network 172.24.1.51
LAN3: Monitoring network 172.16.1.51
* This IP address cannot be changed.
Administrator rights in the operating system
To commission the communication unit, you need to have the appropriate administrator rights to change the
network settings of the computer.
• Contact your network administrator if you are uncertain about administrator rights.
Procedure:
1. Note down the IP address of the computer.
2. Adapt the IP address of the computer to the address range of the communication unit.
4.6.2 Information on Integrating the Inverter into a Local Network
Protecting the local network from cyber attacks
• If the local network is to be accessible via the Internet, you can set up port forwarding via your router or
configure a VPN. Using a VPN is recommended.
• Protect the local network from cyber attacks by means of suitable safety measures such as setting up a
firewall and allocating secure passwords.
Using a static IP address is recommended. You can select the IP address yourself. Use the address range which is
available to your router. If necessary, refer to the router manual.
If you are using a Power Plant Controller for the automatic control of your PV power plant, a dynamic IP address with
DHCP is not possible.

Plants" at www.SMA-Solar.com.
